You have many options when shopping for an enclosure. You can get large enclosures that house an entire automated system or small ones for a single pushbutton or switch. You can buy them in stainless steel, plastic, and many other options. NEMA ratings are an incredible tool to help you decide which option is best suited for your application. Watch this video to learn more about these ratings.

You have many options when shopping for an enclosure. You can get large enclosures that house an entire automated system or small ones for a single push button or switch. You can buy them in stainless steel, plastic, and many other options. NEMA ratings are an incredible tool to help you decide which option is best suited for your application. Today, let’s learn about NEMA ratings. What Is A NEMA rating from AutomationDirect. The National Electrical Manufacturer Association, or NEMA, “uses a standard rating system that defines the types of environments in which an electrical enclosure can be used, and frequently signifies a fixed enclosure’s ability to withstand certain environmental conditions.” The product is defined by its attributes and capabilities. The purpose of an enclosure is to isolate the components inside the enclosure from the surrounding environment, protecting the components from damage and protecting people from injury, so it is important to know the ratings and what they mean! NEMA identifies enclosures with an alphanumerical name for protection classes. The numbers themselves do not denote the degree of protection, which can be confusing, but identify the “specific set of protective characteristics.” Ratings 1 and 2 are for indoor use with a smaller degree of protection but are primarily intended at preventing human ingress. Rating 3 has 6 different variations: 3, 3R, 3S, 3X, 3RX, and 3SX. NEMA rating 3 states that the enclosure is intended for outdoor applications for wiring and junction boxes with protection against windblown dust, rain, sleet, and external ice formation. 3R provides the same protection as 3 but removes the dust protection. 3S provides the same protection as rating 3 but provides the operation of external mechanisms when ice-laden. 3X, 3RX, and 3SX all include additional corrosion protection. NEMA 4 and 4X-rated enclosures are great for washdown applications. 4X provides additional protection from corrosive environments, including those where acidic cleaning agents or disinfectants are used in the washdown process. Be sure to choose a material that is resistant to all the environmental factors your enclosure will be exposed to, as no single material is impervious to all environments. NEMA 5 is intended for indoor use only and protects against airborne dust and non-corrosive liquids. NEMA 6 is intended for indoor or outdoor use and protects against occasional submersion at limited depth, but 6P protects against prolonged submersion at a limited depth [1 meter or less] and adds additional corrosion protection. NEMA 7, 8, 9, and 10 are intended for use in hazardous environments. NEMA 12 is intended for indoor use and is generally used in automation control and electronic drive systems. 12 K-rated enclosures include knockouts. NEMA 13 enclosures are intended for indoor use and protect against dust, spraying of oil, water, and non-corrosive coolant. Functionally, NEMA 3R, 4, 4X, and 12 are the most common types of enclosures for industrial automation applications. However, NEMA ratings do not cover all potential environmental factors for enclosures. Exposures not covered by NEMA ratings include ultraviolet exposure in outdoor applications, in-ground installations, or hygienic requirements for food and beverage applications. Unlike UL ratings that are tested to specific standards, NEMA ratings are self-certified by the manufacturer. NEMA ratings are also subject to change, please consult the latest ratings before purchasing an enclosure. International customers might be more familiar with the IP rating scale. Though the two rating systems are not exactly interchangeable, some correlations may help those familiar with the NEMA system choose the appropriate IP rating for their application. IP ratings are two digits: the first denoting the Ingress Protection versus solid objects such as dust, the second versus liquids. The higher the number, the higher the degree of protection. Also, if the rating ends on 9K, it indicates the highest liquid protection under high pressure and high temperature at close range. Whatever you decide you need in the realm of industrial and automation controls, AutomationDirect.com is your best resource. NEMA ratings are available in the documentation and prominently displayed on the website for every NEMA-rated product. Our top-rated customer support team is here to help you with any questions.
